Abstract (en)
[origin: EP3709431A1] Disclosed is a secondary battery charging and discharging apparatus. The charging and discharging apparatus for performing an activation process of a secondary battery includes a plurality of compression plates disposed to be spaced apart from each other by a predetermined distance to form a cell insert space into which a secondary battery cell is inserted, the plurality of compression plates moving to reduce the separated distance to press a body of the secondary battery cell; a slip sheet having a sheet shape and formed to include attachment portions attached to top ends of the compression plates and a folding portion formed by folding a region between the attachment portions to be interposed in the cell insert space; and a slip sheet fixing unit provided to be attached to and detached from the top end of the compression plate in a fitting and releasing manner in a state where the attachment portions of the slip sheet are interposed therein.
